Explain how you know that 67 rounded to the nearest ten is 70.
Because when rounding to the nearest ten you look to the right to the ones place.  If the number in the ones is 4 or less you let the ten rest at 60.  If the number in the ones is 5 or more you raise the score of the number in the tens to 70.  7 is more than 5 so it rounds up to 70.
